FGP4X复合式高速排气阀概述 I. Overview of FGP4X composite high-speed exhaust valve
FGP4X compound high-speed exhaust valve, GP4X power high-speed exhaust valve : It can prevent the floating ball from being blown up in high-speed air flow to block the exhaust port and cause the exhaust valve to fail. In order to prevent the valve port from being blocked, the traditional high-speed inlet and exhaust valve is provided with a protective sleeve at the inlet, which makes the valve complicated in structure.
复合式高速排气阀 三大特性: Three characteristics of composite high-speed exhaust valve :
1. High-speed exhaust when filled with water, not afraid of plugging.
2. Inhale at high speed when discharging water.
3. Trace exhaust under pressure.
FGP4X复合式高速排气阀工作原理 Working principle of FGP4X composite high-speed exhaust valve
是利用伯努利理论制造的一种能够在气流下保持全开，当实心水柱上升时，浮球能够马上被浮起并严密封闭排气口的浮球式排气阀。 FGP4X composite high-speed exhaust valve is a kind of floating ball exhaust that can be kept fully open under the air flow using Bernoulli theory. When the solid water column rises, the float can be immediately lifted and the exhaust port is tightly sealed valve. 采用特定的浮球直径，使得它产生的气流动力能维持浮球在气流经过时开启（悬浮），实心水柱上升时产生的浮力又能使其浮起，配之入口处以一个合适角度的圆锥体，可做到不管气压多大、气流速度多高，排气口也不会被吹堵。 The compound high-speed exhaust valve adopts a specific floating ball diameter, so that the airflow power generated by it can keep the floating ball open (suspended) when the airflow passes. A cone with an appropriate angle can prevent the exhaust port from being blocked regardless of the air pressure and air velocity.

FGP4X复合式高速排气阀安装位置 Five, FGP4X composite high-speed exhaust valve installation position
安装于有可能高速进排气的地方，充水时高速排除管道中的空气，在管道放空时吸入空气保持排水通畅，管道正常工作时可以不断地排除析出的空气。 The compound high-speed inlet and exhaust valve is installed in a place where high-speed intake and exhaust are possible. When the water is filled, the air in the pipeline is quickly removed. When the pipeline is emptied, the air is sucked in to keep the drainage smooth. When water hammer is likely to occur, air is automatically entered to avoid negative pressure and prevent or slow down the harm of water hammer.
